Heat oil in a large non-stick skillet over medium-high heat.
Add butternut squash and saute for about 7-8 minutes, stirring occasionally.
Be sure to keep a close eye on the squash so it doesn't burn.
Add in minced garlic and cumin.
Season with sea salt and pepper to taste, then stir to combine.
Reduce heat to medium-low and cover the skillet with a lid.
Cook for about 5 minutes more, until the squash is crisp tender - stirring once or twice.
Garnish with lime wedges, cilantro and green onions. Enjoy!
